Abstract
The effect of mutual coupling between two cylindrical and parallel wires was studied at high frequencies. Currents into two wires were separately supplied with a different phase angle from two current sources.The vector diagrams for the voltage for the two-wire system were drawn under various phase differences and were compared with those of a single wire system. The inductive and resistive components of the voltage in the two wire-system were analyzed from the voltage differences of both systems. These voltages were also considered theoretically using the equivalent circuit and electomagnetic theory.
As a result, it was found that the increase of inductive components of the volage is nearly zero at the phase angles of 90° and 270° different from that of a single wire system. This result suggests that the increase of proximity resistance can be suppressed considerably even at a high frequency.
